SAFAETY SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 739,226,dated'september 15, 1903 Application filed May 28, 1903, Serial Nor159,185. (No model.)

To all whom it may concern:

Be it known that I, OSMER W. SANBORN, a citizen of the U11 itedStates,residing at Hewins, in the county ofv Chautauqua and State of Kansas,have invented new and useful Improvements in Safety Snap-Hooks,'of'whichthe following is a specification.

This invention relates to snap-hooks of the safety type for use inconnection with harness generally or for other purposes;-, and theobject of the same is to provide an efficient and durable snap-hookwhich may be easily and quickly operated to engage or release adeprevent movement thereof.- 7 I The invention further consists in thedetails of construction and arrangement of the several parts which willbe more fully hereinafter described and claimed.

In the drawings, Figure 1' is a perspective view of a snap-hookembodying the features of the invention and shown open. Fig. 2 is avertical longitudinal section thereof, showing the mousing-piece orlatch closed.

Similar numerals of reference are employed to indicate correspondingparts in the views.

The numeral 1 designates the shank of the hook, having a loop or eye 2at one end for attaching purposes, and at the opposite end ahook 3 ofpractically circular form projects from the shank and has a slot orbifurcation 4 formed therein, in which a mousing-piece or latch 5,corresponding in curvature to the members of the hook 3, ispivotallymounted for rotating movement, the pivot 6 passing through themousing-piece or latch 5 at a point near the center thereof.

To limit the opening movement of the mousing-piece or latch 5, thelatter is formed with a shoulder 7 to engage the lower reduced end 8 ofa catch 9, depressible into the shank and lower portion of the'hook 3.The upper terminal of the catch 9 has a flat spring 10 extendingrearwardly therefrom and secured to the shank 1 adjacent to the eye orloop 2/ The spring 10 projects upwardly and operates to restore thecatch to normal position. At the point where the forward extremity ofthe spring 10 joins the upper end of the catch an angularly-disposedface 11 is formed for al-' lowing a clearance for the terminal of theclosing extremity 12 of the mousing-piece or latch'5. .When themousing-piece or latch 5 isclosed, the lower end thereof is engaged bythe lower reduced terminal'S of the catch 9, as clearly shown by Fig.2,and in order to release the mousing-piece or latch it is necessary todepress the spring 10 and catch 9 to clear the extremity 8 from thelower end of said piece or latch. After such clearance or disengagementof the catch from the mousing-piece or latch the latter may be opened, v

as shown by Fig. 1, and a ring, loop, or other device may be freelyinserted in the hook 3.

When the mousing-piece or latch is open, the

lower portion thereof projects upwardly With-' in'the opening of thehook 3, and a pressure on said projecting part of the mousing-piece orlatch by the ring, loop, or other device placed in engagement with thebook will spirit of the invention.

Having thus fully described theinvention, what is claimed as new is- 1.A snap-hook, comprising a shank witha hooked extremity, a mousing-piecerotatably mounted in said extremity, and a-spring-ac: tuated catcharranged to engage both extremities'of the mousing-piece. A

9. A snap-hook, having a shank with a slotted hooked extremity, amousing-piece rotatably mounted in said extremity and provided With ashoulder, and a'spring-actuated catch arranged to engage the extremitiesof the mousing-piece and also the shoulder of the latter.

In testimony whereof I affix my signature in presence of two witnesses.i
